path-traversal is a skill for Claude Code from securityfortech/hacking-skills. It costs 118 tokens per session (1,974 once invoked), scanned A, original, no licence file.

A security-testing guide for path traversal and file inclusion, where crafted file paths make an application read or load files outside the intended location.

In plain words
What is it for?
Use it to test web parameters and PHP include or require behavior for local files, remote files, Unix paths, Windows paths and encoded traversal sequences.
Why use it?
It helps uncover unsafe handling of paths in URLs, cookies and hidden fields, including encoding tricks that can evade simple filters.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

path-traversal scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
